toJson method

@override Map<String, Object?> toJson()

Serializes the part to a JSON map.

The returned map must contain a key matching typeKey with a unique string identifier for the part type. See defaultPartConverterRegistry for default part types.

Implementation

@override
Map<String, Object?> toJson() => {
  Part.typeKey: type,
  _Json.content: {
    if (name != null) _Json.name: name,
    if (mimeType != null) _Json.mimeType: mimeType,
    _Json.url: url.toString(),
  },
};
